known that l, ALLEN CLYMER AUB- rm a citizen of the United tates and a resident ct Syracuse, in the county oi? Ononchines such as that of my pending applicatiled Oct. 5, 1915, and has tor its object iarticularly sim le, eliicientand economical frame COHSUHCHOH for Dressing machines; and the invention consists in the in features, and in the combinations and constructions hereinafter set fa'th claimed.

in describing invention, reference is had to the accompanying drawings in wh ch like characters Qdesignates corresponding parts in all the views.

1. his pi 1g machine comprises a frame, a stationar essing element or buck supported by the "trains, a movable pressing element or head. a movable snpportior the pressing head. and means for operating the movable supp rt.

The frame, as here illustrated, comprises a table. front and rear legs supporting the table. the table and the legs being provided with conlplemental bearing faces which'incliue downwardly and inwardly and preferhbly have high or raised portions which ongage when the parts are assembled, and fast ening members extending through the bearing faces. These inclined bearing faces insure snug and rigid engagement of the parts and the high or raised portions thereof eliminate the neces ity of accurate machinas it is not necessary that the faces be fitted throughout their entire area. but only at their high or raised points which can be made to come together without machining. In this form of my invention there are two front legs constructed as a single unit, and a single rear leg located midway between the sides of the frame.

1 designates the table; 2' the front legs, and 3 the single rear leg, the table being here shown as a plate having bearing faces 5 6. The bearing faces 5 are located at the front corners of the table, on the under side thereof, and are inclined downwardly and rearwardly or inwardly toward the center of the frame, out of a horizontal lane, and have high or raised portions 7 which project farther below the table than the remaining parts of said bearino faces. As here illustrated the raised ortions 7 extend along the margins of the aces 5 so that the central portions of the faces 5 are depressed.

The bearing face 6 is located on a web 8 depending from the rear side of the table and is inclined downwardly and slightly 'inwardly or forwardly out of a vertical plane, and is provided with raised or high portions 9 at its opposite ends. Reinforcing webs 10 extend from the opposite ends of the web 8 on which the bearing surface 6 is provided, to the hearing faces 5. The table 1 is also formed with a rearwardly eXtendinghori zontal flange or shoulder 11 located along the upper edge of the face 6.

The front legs 2 are cast as a unit in one iece and are connected at their upper ends y a web 12 and at their,lo.wer ends by a brace 13 which'curves or convenes inwardly toward the rear side of the machine.

The front legs 2 are provided at their upper ends with bearing surfaces 14 which are complemented to the bearing surfaces 5 and inclined out of a horizontal plane. the planes of these faces 14 being arranged at a right angle to a plane containing the axes of the legs 2 which axes preferably are not perpendicular but diverge or spread toward the lower ends of the legs.

The rear leg 3 is a pillar in the form of a channel in cross section and is arranged with its channel facing rearwardly. Said leg is provided with an extension at its upper end. constituting a bracket 15 which carries a bearing 16 at its upper end. the hearing being located substantially in a vertical plane intersecting the leg 3 throughout its length. The rear leg is provided with a bearin faced? inclinorl out of a vertical plane and arranged in position to coact with 'thebearing face 6 of the table, the bearing faces 6 and 17 each having high or raised said taccs and 17 trom shearing strain.

Fastening members as bolts 19,. 20 are passed through the central depressed portions of the bearing faces 5 and through the bearing faces 14 ot' the Front legs, one of the bolts as 19 of each set extending through a slot 21 formed in the leg and opening through the rear edge of the companion bearing face 14.

One of the bolt holes .22 through one of the bearing faces 5 of the table is a slot. The bolt which passes through this slot 22 also serves to secure to the table, a bracket which is mounted on the table and supports the lower buck. This bracket is secured at three points by bolts passing through slots 23 in the table. the slots 22, 23 permitting a limited adjusting movement of the bracket.

Fastening members as bolts 2+ are passed through the high points of the bearing faces 6 and 17. The front and rear legs are connected by detachable braces 26 bolted at their front ends at 27 to the legs 2, respectively and at their rear ends 28 to the rear leg 3, the rear leg being provided with laterally extending webs 29 to which the braces 26 are bolted.

The rear leg .is also provided with a slot 30 at its lower end and with forwardly ex;- tending flanges 31. on opposite sides of the slot to which the operating lever to be described is pivoted.

32 designates the lower pressing element or buck.

33 is the upper pressing element or head.

34 is the bracket previously referred to which supports" the lower back and which in turn is mounted upon the table 1. and secured thereto by the bolts passing through '37 lower end of the rear leg 3, an arm 39 rigid with the lever 37 and extending upwardly the slots 22, 23.

35 is the support for the pressing head 33, this support being a lever mounted between itsends on a shaft 36 arranged in the beare ing 16, the front arm of the lever carrying the pressing head and the -rear arm of.

through the slot 30 and forming one link of a toggle, and a toggle link 40 pivoted at 41 to the upper end of the arm 39 and at 462. to the rear end of the support lever The downward movement of the lever 37 carries the joint 41 of the toggle toward the dead center line thereof, and such movement is against the action of a spring 43.

An adjustable toot piece le mounted on the front end of the lever 37, said foot piece being movable into the space in front of an intermednue part of the brace 13 connecting the front legs The toggle link 40 includes end pieces or bearings 4-5, l6 mounted on the pivots all, 42 respectively and. a rod 47 threading into the upper bearing member 4-6, the rod being held in position by a lock nut i3 and being operable or rotatable by a hand Wheel ll). the hub of which bears against the lower end piece l5. the hand wheel being fixed at 50 to the rod.

Obviously, by turning the wheel l9. u loosening oi the nut -18, the length of the link l-(l can be increased or decreased. Instead of the lock -'nut 48, the rod 47 may be locked by a spring pawl 48 coacting with ratchet teeth on the periphery of the wheel 49.

in order to limit the movement of the toggle joint 4-1 relative to the dead center line of the toggle, the end piece i5 is provided with front and rear arms 51, 52- extending downwardly in the front and in the rear of the upper end of the toggle link 39 and carrying adjustable stops screws 53, 5t

pon

.which engage at 5'5 and. respectively with the toggle link 39;

Obviously. the stop will limit the move ment ol' the toggle joint into and beyond a straight line and the stop will limit the breaking movement of the toggle joint out oi a straight line.

The operating means also includes a weight 57 mounted on the pivot a2 and having forwardly extending arms 58 pressing upwardly on the rear arm of the supporting lever 35 for the mov: ble pressing head 33.

The steam system of this machine is the same as in my pending a 'iplication referred to and includes the flexible coupling This machine is advantageous in that its parts can be assembled without accurately machining faces which engage.

It is further advantageous in that owing to the arrangement of its rear leg, the'stress due to the pressing operation of the movable pressing head, extends vertically of the central rear leg orpillar and hence the operation of the machine doesnot tend to tear apart or loosen any of the part-s in the machine.
